'wIn'E-onIMPING TOOL.

Application filed June 6,

My invention relates to tools for crimping fence wire. When the fence is first erected, the wires are crimped at intervals for the purpose of permitting the wire to expand or contract as influenced by change in temperature. All horizontally running wires in woven wire fencing are thus provided with a crimp between each vertical stake or upright. These crimps also serve to permit the sudden expansion of the wire fencing when it is subjected to excessive strain as by cattle leaning against the same.

It is evident that after the fencing has been erected sometime and passed through several seasons of warn and cold weather these crimps will gradually disappear and the fence will sag and become loose and bagg The object of the present invention is to provide a tool for recrimping the wires in order to remove the sagging so that the fence will again be made taut without the trouble of loosening the wires from the posts. l/Vith this tool a considerable length of fencing can be stretched in a very short time and have the appearance of a newly erected fence.

In the accompanying drawing, one embodiment of the invention is illustrated, and

Figure 1 shows a side elevation of the crimping tool, and

Figure 2 is a section on the line 22 of Figure 1.

The tool has the general appearance of a: pair of ton s having two limbs 10 and 11 joined by a pivot pin 12. These limbs form handles 13 and 14., respectively, on" one side of the pivot pin 12 and jaws 15 and 16 on the other side thereof. The jaw 15 terminates with a gripping portion 17 of V shapec cross section, as best seen in Figure 2, and the jaw 15 terminates with a gripping memher 18 having a sharp ridge 19 extending parallel to the longitudinal axis of the jaw of the same transverse cross section as the gripping member 17 so that, when the jaws are brought together, the ridge 19 which runs longitudinally of the aw will engage in the V-shaped groove formed in the gripping member 17.

The use of the tool is clearly shown in Figure 2. The operator holds the tool by the handles 13 and 14 and grips the wire to be crimped between the gripping members 17 and 18. When the handles are moved towards each other, pressure is exerted by the gripping members upon the wire 20 and the 1924. Serial No. 718,300.

wire will be bent to form a V-shaped crimp, as seen 1n this figure. It should be noted that the edge faces 21 ofthe diverging side portions of thejaw 17 are flat, as shown in Figure 2, and are disposed in a plane parallel to the axis of the jaw for flat engagement with the wire 20 at opposite sides of the jaw 18 while the crimp is being formed in the wire. It should be further noted that the side portions of the jaw at the int-ersections of the edge faces 21 with the inner and outer faces 17 and 17 of the jaw are rounded. Thereforethere is no danger of the wire eing sliced through by contact with a sharp edge as would be the case if the edge faces of the side portions of the jaw were disposed at right angles to the axis of the wire.

It is evident that instead of furnishing only one groove and one ridge of comparatively great depth several smaller grooves and ridges may be provided on the jaws. These grooves and ridges will then preferably run in the longitudinal direction of the jaws 15 and 16.

Having thus claim:

A tool for crimping fence wires comprising crossed limbs pivoted together attheir point of crossing, the portions of the limbs at one side of the pivot constituting handles and the portions of the limbs at the opposite side of the pivot constituting mating jaws and terminating in elongated gripping heads, the head of one jaw being V-shaped in cross section to provide diverging side portions, the said sidepo'rtions having fiat edge faces disposed in a common plane and extending ,I' arallel to the longitudinal axis described the invention, I

of the jaw and at their sides rounded into the inner and outer faces of the diverging portions, the head of the other jaw being rectangular in cross section and having fiat faces converging to form a central ridge extending parallel to the longitudinal axis of the jaw and adapted to fit between the sideportions of the head of the first ja-w with the outer side edge faces of the first jaw disposed beyond the outer side edges of the said converging faces of the second jaw whereby a wire disposed transversely between the heads of the jaws may be crimped when pressure is applied to the handles.

In testimony whereof I aflix my signature.
